It has been an unusually wet summer here in Utah. I was trying to film raindrops during a particularly violent thunderstorm and kept forgetting to disable my flash. This was one of the results.
It wasn't until I moved away from BYU campus that I got to know other parts of Provo a lot better. This water park is located in central Provo and these two slides are the main attraction for everyone over the height requirement of 48'. :)
